The first connectingrod 411 can include a first end 413 and a second end 414 opposite to thefirst end 413. The first end 413 of the first connecting rod 411 candefine a sliding slot 415. In at least one example, the firstpositioning pin 212 can pass through the sliding slot 415 and have thetwo ends respectively received in an associated receiving hole 218. Thefirst positioning pin 212 can slide along the sliding slot 415 androtate in the sliding slot 415. The second end 414 of the firstconnecting rod 411 can be fixed to the first supporting rod 412. In atleast one example, the first supporting rod 412 can slope with respectto the first connecting rod 411. In at least one example, the firstsupporting rod 412 can be substantially perpendicular to the firstconnecting rod 411. The first supporting rod 412 can include a number ofsleeved rods 416. Thus, a length of the first supporting rod 412 can beadjusted via adjusting positions of one or more rods 416 with respect tothe other rods 416. The first supporting rod 412 can be configured tosupport the base 10 and the electronic device 2. In an initial state,the first connecting rod 411 can be substantially perpendicular to thefirst shaft rod 211, and resist the first cover 112 (see FIG. 5).

To support the electronic device 2, the first supporting arm 41 can beexerted to cause the first positioning pin 212 to rotate and slide inthe sliding slot 415 until the first connecting rod 411 is substantiallyparallel with the first shaft 21. The first elastic member 312 canresile to bring the first shaft 21 away from the first cover 112; thefirst shaft 21 can bring the first connecting rod 411 into the firsthollow portion 116, and bring the first washer 311 toward the firstlimiting member 12. The first limiting groove 122 can exert a force onthe first washer 311, causing the first washer 311 to be deformed. Thefirst washer 311 can resile to resist the first limiting groove 122,thus the first washer 311 can be limited in the first limiting groove122. The first shaft 21 and the first connecting rod 411 can bepositioned relative to the base 10. The first supporting rod 412 canform the desired angle with the base 10 and be positioned at the desiredangle.
